A team uses Helm to deploy a Kubernetes application. They need to change a configuration value (such as the number of replicas) without editing the chart's templates. They want to apply the change to the existing deployment and be able to roll back if needed. What should they do?

Delete the release and reinstall with the new values.

Edit the chart's `values.yaml` file and run `helm install` again.

Use `kubectl scale deployment` directly.

Use `helm upgrade` with `--set replicas=5`

In a containerized application with multiple replicas, which orchestration feature allows clients to reach any healthy instance without knowing its individual IP address?

Service discovery and load balancing

A team manages a Helm release for a production application. They need to update the application to a new version, but they want to ensure that if the upgrade fails, the previous version is automatically restored. They also want to limit the number of historical revisions kept to reduce etcd load. What should they do?

Use `helm upgrade --force` and manually delete old revisions.

Use `helm upgrade --wait` and rely on the cluster's self-healing.

Use `helm upgrade --atomic` and set `--history-max` to a reasonable number.

Use `helm upgrade --recreate-pods` and set `--history-max`.

An organization wants to deploy a complex Kubernetes application that consists of multiple Deployments, Services, ConfigMaps, and Secrets. They need to version the entire application definition, allow easy rollback to a previous version, and share the deployment package with other teams. Which tool should they use?

Docker Compose with a YAML file that defines all resources.

A shell script that applies all YAML files in a specific order.

Helm with a chart that contains all the Kubernetes manifests and a values file for configuration.

Kustomize with a base directory and overlays for each environment.
